Representative Main Circuit Wiring
An example is given in the figure below of typical wiring of the main circuit.
Power Feed Sequence Setting
Keep the following points in mind when designing the power feed sequence:
• Design the power sequence so that the power goes OFF when a servo alarm
signal is output (see the above circuit).
• Push the POWER button continuously for at least 2 seconds. The servo
amplifier outputs a servo alarm signal within a maximum of two seconds of
power ON. This is necessary for initial setting of the servo amplifier.
